{"product_id":"stage-2-top-mount-twin-turbo-system","title":"Stage 2 Top-Mount Twin Turbo System","description":"The On3 Performance 4vTT-1 is a bolt-on twin turbo system engineered specifically for 1996-2004 Ford Mustang Cobra and 2V\/4V 4.6L models. It utilizes a Stage 2 configuration with top-mounted turbochargers, custom forward-facing headers, and a stainless steel hot-side to support power goals of 1000+ HP.\n\nInstallation requires a tubular K-member, such as those from UPR or Team Z, along with matching A-arms and coil-overs, as the factory K-member lacks the necessary clearance for this system. Other supporting components typically required for a complete setup include an upgraded fuel system (pump and injectors), a mass air flow sensor kit, a coolant crossover kit, and a power steering relocation reservoir.\n\nEach kit includes two 44mm wastegates, two 50mm blow-off valves, a 3-inch air-to-air intercooler with laser-formed brackets, custom oil feed\/drain lines, and silicone couplers with t-bolt clamps.","brand":"On3 Performance","offers":[{"title":"Default Title","offer_id":52689319002424,"sku":"4vTT-1","price":3199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687478613.webp?v=1784905068","url":"https:\/\/store.motormia.co\/products\/stage-2-top-mount-twin-turbo-system","provider":"MOTORMIA","version":"1.0","type":"link"}
